METEOROLOGY WATER. 811 



It is shown that in fluids of low density, whicli compare well witli the density 

 of commercial preparations of nicotin, practically the same results are ob- 

 tained with all 3 methods. Substances with a heavy density, however, behave 

 differently. The lowest results were obtained with Toth's method, with Biel's 

 next, and the highest with the Ulex method. Juices containing from 7 to 10 

 per cent of nicotin may show differences as high as 1.5 per cent when Toth's 

 and Ulex's methods are compared. 



Laboratory handbook for the oil and fat industry, J. Maecusson (Labora- 

 toriumshuch fiir die Industrie der die und Fette. Halle, 1911, pp. XII+146, 

 figs. 21). — This is principally a book of methods for the examination of fats, 

 oils, soaps, varnishes, lacquers, oil colors, oxidized and blown oils, and lubri- 

 cating oils. 



The fatty oil and the wax of coffee beans, H. Meyee and A. Eckeet 

 (Monatsh. Chem., 31 (1910), No. 10, pp. 1221-1251) .—The results are reported 

 of a physical and chemical examination of these substances in the coffee bean. 



Lumbang oil, R. W. Daenee (North Dakota Sta. Spec. Bui., 2 (1913), No. 19, 

 pp. 337-339). — Analyses of nuts of the lumbang tree, Aleurites triloba or A. 

 moluccana, obtained from the Philippines and the Hawaiian Federal Station, are 

 reported, together with analyses of the oil therefrom in comparison with values 

 obtained by other investigators under the name of " candlenut oil." There 

 seemed to be a wide variation in the iodin numbers as determined by the dif- 

 ferent analysts, which may be due to the fact that oils derived from different 

 species of the same family are being sold under one name. The drying prop- 

 erties of the oil indicated that it can well be used in the. paint and varnish 

 trade. See also a previous note (E. S. R., 28, p. 714). 



METEOROLOGY— WATER, 



Weather and water, M. Hoffmann (Jahresher. Landtc, 27 (1912), pp. 1- 

 2It). — Recent investigations on these subjects are classified and reviewed as 

 usual. 



The action of the wind and its significance in agriculture, H. K. Stamm 

 (Intcrnat. Mitt. Bodenk., 3 (1913), No. 1, pp. 50-66; abs. in Rev. Sci. [Parisi, 

 51 (1913), II, No. 12, pp. 367-370).— This is a discussion of the subject based 

 upon a report by Free and Stuntz (E. S. R., 25, p. 424), emphasizing especially 

 the means which may be adopted to reduce the damage done by wind erosion. 



The relation of the soil to meteorological factors. III, IV, E. G. Loske 

 (Trudy Selsk. Khoz. Met., 1912, No. 9, I, pp. XIV +105-334) .—This is part 1 of 

 a review (in the Russian language) of worls in agricultural meteorology and 

 related questions, issued by the Meteorological Bureau of the Scientific Com- 

 mittee of the Ministry of Agriculture of Russia. The review contains a bib- 

 liography of the literature of the subject. 



The influence of climatic conditions on agriculture in Germany, A. 

 ScHNiDER (Landw. Eefte, 1912, No. 1, pp. 27; abs. in Internat. Mitt. Bodenk., 3 

 (1913), No. 1, p. 74). — This article deals with the different active climatic fac- 

 tors, such as rainfall, temperature, wind, etc., especially in their relation to 

 various farm operations. 



The climate of Utah as a resource, A. H. Thiessen (Bien. Rpt. Utah Con- 

 serv. Com., 1 (1913), pp. 132-145, figs. 3). — This is a review of the climatic 

 conditions of Utah, in which it is stated that the mean annual temperatures 

 range from 40° F. in the extreme north to nearly 60° in the extreme southern 

 part of the State. The annual precipitation varies from 6 to 20 in., most of 

 the moisture falling during the winter and spring. A large part of this is said 

 to be conserved for irrigation purposes.
